NOSE-GRIP FOR EYEGLASSES.

To all whom it may concern.'

Be it known that 1, THOMAS E. CARPEN- TER, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Nose-Grips for Eyeglasses, of which the following is a specification, reference being had therein to the accompanying drawings.

Like reference characters indicate like parts.

Figure l is a front elevation of a pair of eye-glasses provided with my improved nose grip. Fig. 2 is side elevation of said nose grip. Fig. 3 is a view of said nose grip as seen in elevation. Fig. 4 is the same as Fig. 3, except that the nose grip is shown as mounted upon the end of the bridge, the latter being represented as seen in cross section upon the line z 2 of Fig. 5. Fig. 5 is a top plan view of the end of the bridge and lens-clamp. Fig. 6 is a front elevation of the same. Fig. 7 is a cross sectional view on line 'y y of Fig. 6. Fig. 8 is a top plan view of the end of the bridge and of the lensclamp with my improved nose grip mounted thereon. Fig. 9 is a cross sectional view of the nose-pad as seen on line x of Fig. 8.

My invention is a nose grip for eye-glasses, and relates particularly to the class of lingeroperated nose grips.

It consists of the novel construction and combination of the several parts thereof as herein after described and as specifically set forth in the claims.

In Fig. 1 the reference numeral 1 represents the lenses of a pair of eye-glasses and 2 is the bridge connecting said lenses. Each end of the bridge adjacent to the lenses, respectively, comprises three parts,a stud or disk-like body 3, two lens-supporting prongs 4 and two parallel ear pieces 5, commonly called the straps. The straps 5 have two oppositely located holes 6 and 7, in alinement with each other, the hole 6 being provided with a screw-thread, and the hole 7 being countersunk for the reception of the head ot' a screw. Each pair of straps 5 receives between them the edge of a lens 1 and a screw 8 passes through a hole in the lens 1 made therefor, the threads of said screw engaging with the threaded hole 6 of one of said straps, and the head of the screw being seated in the countersunk hole 7 of the other of said straps.

ln the edge of the stud 8 there are the4 Specification of Letters Patent.

notch 9 and socket 10, the notch 9 opening into the socket 10, but of smaller dimensions. This combination of' the notch 9 and socket 10, results in the formation of a lip, as plainly seen in Fig. 4, extending parallel to the upper and lower` plane surfaces of the stud. rlhe stud also has in its lower side the small round hole 1 1, which is located out of vertical alinement with the notch 9 and socket 10.

The nose grip is designated as 12. On its outer end the nose grip has a tubular piece 13 loosely mounted and held from longitudinal displacement by the headed end 14 of the said grip. The tube 13 is therefore capable of a swiveling action on the nose grip 12, the latter being at and near its end cylindrical in shape. A. nose-pad 15 is located diagonally upon the tube 13 and is fastened by solder or otherwise. The bearing surface of the pad 15 is preferably corrugated longitudinally, as seen at 16, or otherwise roughened in order that it may have the requisite frictional contact with the nose.

The whole nose grip is made o1' tempered metal so as to have suliicient resiliency l'or the spring action hereinafter explained. i/Vith the exception o1' the end adjacent to the head 14, the nose grip is preferably made of flat stock.

The end ol' the nose grip opposite to the head 14 is i'ormed into the bow shape, illustrated at 17, and is also curved as shown at 18. r1`he end o1' the bow 17 has the terminal bent pin 19, which extends into close proximity with the straight or central portion o1' the nose grip and at a right angle thereto. An L-shaped hook 20, 21, extends 'l'ronisaid straight portion oi' the nose grip 12, in the same plane with the pin 19, within the bow portion 17, the end ol the pin 19 being in close proximity with the end of the hook 21. The portion ol' the bow 17 adjacent to the pin 19 is bent slightly sidewise, as illustrated in Figs. 2 and 8, and whereas the notch 9 and socket 10 are directed radially inward, as shown in Figs. 7 and 8, the hole 11 is located out o1' vertical alinement with the notch 9 and socket 10.

The parts are assembled as follows. The hook 20, 21, is inserted in the notch 9 and socket 10, as represented in Figs. 4 and 7, and thus that portion 21 olI said hook which is parallel to the straight portion ol' the nose grip 12 underlies the outer surlace o1' the stud 3, as appears by the dotted line gig in Fig. 5 adjacent to the curved edge Yol the l engagement with the hole 11, as most plainly seen in Fig. 4, the relative position ol' said pin being clearly exhibited in Figs. 7 and 8.

The bent end 21 o'l` the hook, when engagedV as in Fig. 4, prevents vertical displacement of the nose grip and maintains it in the position there shown, though not in any manner interfering with the swiveling movement ol' the hook in the stud. The partial rotation oi said hook is limited by the converging walls ol' the socket 10 and the contact ol' the parts 20, 21 ol' the hook therewith. The engagement of the pin 19in the hole 11 oll the stud 3 prevents any lateral detachment oi' the nose grip 12 from the stud 3, though not interfering with the proper swiveling movement of the nose grip.

The portion ol the bows where marked 17 in Figs. 1, 3 and 4, being bent, as shown at 18, adapts them lor use as finger-pieces. The nose-pads are normally in the position shown in Figs. 1 and 8, having a spring-pressure inwardly against the two sides ol'l the nose ol' the wearer, and at that time the two bows or linger-pieces 17 extend outwardly toward the lenses 1, respectively.

To detach the eye-glasses 'from the nose, the two bows or finger pieces '17, are pinched slightly vtoward each other in an inward movement by the thumb and `foreiinger, and consequently, as the hook 20, 21, swivels in the notch 9 and socket 10, the nose-pads 15 move apart out oll contact with tlie nose and the eye-glasses are then removed from their wearing position.

The spring-action required l'or maintaining the proper 'frictional contact oi' the nosepads 15 with the nose, is ailorded by the end of the bow 17. l/Vhen the finger-piece 17, is moved, as above described, in the direction indicated by the arrow 22 in Fig. 8, the straight portion 12 oi the nose grip turns on the hook 20, 21, as a center, but as the end of the bow 17 is confined by the engagement of the pin 19 in the hole 11. ol' the stud 3 and said hole is eccentric to the notch 9 and socket 10, said end ol' the bow 17 is put under tension, so that whenever the said finger manipulation ceases and the nose grip is i'ree to act, it resumes automatically its normal position shown in Fig. 8.

The swiveling action oll the tubes 13 on the outer cylindrical portion oll the nose grip 12 enables the nose-pads 15 to assume automatically such angular positions as to conl'orm them to the shape ol' the nose. This nose grip is easily detached l'rom the stud 3, whenever desired, by first withdrawing the pin 19 l'rom the hole 11 ol' said stud, and then withdrawing the hook 20, 21, from the notch 9 and socket 10.

To vary the tension of the spring, the end ol'V the bow 17, where the pin 19 is, can be slightly bent by, the thumb and foreiinger, or by a suitable tool, either in the direction indicated by the arrow 23 in Fig. 2 to increase the tension, or in the opposite direction to lessen the tension.
